Abstract

Ku band satellite signal repeating technology just altering a polarization of the repeated signal is applicable for any kind of satellite broadcasting service in geographically shadowed area due to high-rise buildings, trees, and so on. This paper focuses on the design of high polarization discrimination antenna satisfying polarization characteristics with respect to field pattern and frequency band. Designed antenna for the enhancement of axial ratio and polarization discrimination characteristic shows good performance for satellite broadcasting service repeating system.
